Pennsylvania's U.S. Sen. Pat Toomey is turning the big 5-0 next month and to celebrate the milestone he's having a party! To attend the soiree at the Capitol Hill wine bar, Sonoma, you just have to pay a small admission fee.

Politico, who broke the news of the bash, reported Wednesday that Toomey's Nov. 16 party (his actual birthday is the next day) costs $500 for an individual and $1,000 for a PAC. The event appears to be pretty high profile. Politico reports that the party will be attended by some of Toomey's Senate besties, including Sens.John Cornyn of Texas, John BarrassoofWyoming, Ron Johnson of Wisconsin, Dan Coats of Indiana, Jim DeMint of South Carolina and Mike Leeof Utah.

Toomey's select role on the deficit fighting supercommittee makes the birthday party of particular interest. A number of watchdog groups called on the 12 members of the panel to forgo fundraising while on it. The recommendation from the panel is due the week after the bash.

Adam Smith, spokesman for Public Campaign, a group that calls for less special interest money in politics, asked in an email, "Will a lobbyist jump out of a cake?"
